The answer is <span>The increased nitrates from the fertilizers leech into the water and cause algal blooms, which take oxygen out of the water and this suffocates fish.</span>.
Algae blooms are the consequence of large amounts of farm
fertilizers in the rivers, which increases nitrates level in the water. Algae use the presence of increased nutrients
and enhance their own growth. It is known that they produce
an oxygen in the photosynthesis, so it is not a problem while they are
still alive. But when these organisms die, their decomposition begins. For the
process of decomposition, the oxygen is needed and ultimately it will be depleted
from a body of water. This could lead to the death of aquatic animals, such as fish, that
depend on oxygen.
Answer:
The deceleration of the plane is 0.25 m/
.
Explanation:
Deceleration is the converse of acceleration.
From first law of motion, we have;
v = u + at
where: v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.
Thus,
v = 50 m/s
u = 80 m/s
t = 120 s
50 = 80 + 120a
50 - 80 = 120a
-30 = 120a
a = 
= -0.25
a = -0.25 m/
The deceleration of the plane is 0.25 m/.
Answer:
Paleontologists study fossils so that we can understand the evolution's from past species to the current ones. It also opens a window to discovering exactly how long earth has been around by finding out the age of the fossil itself. Though paleontology has been in the decline recently, and i'm sure we haven't found out all we need to know from these fossils.
Explanation:
the answer is four hope this helps :)
If the Earths polar Ice melts the ocean levels will increase because of the increased amount of water. Some peninsulas and islands would decrease because they would sink from the risen water.
